DOUBLE-TREE.

SPECIFICATION forming part of Letters Patent No. 231,946, datedSeptember '7, 1880.

Application filed February 25, 1880.

To all whom t may concern:

Be it known that I, WILLIAM W. WINEGAR, a citizen of the United States,residing at Chambersburg, in the county of Pike and State of Illinois,have invented certain new and useful Improvements in Double-Trees; and Ido hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters andtigures ofreference marked thereon.

Figure l-of the drawings is a perspective View of my invention, and Fig.2 is a front elevation of the same, partly in section, showing in brokenlines the different positions of the pivoted arms composing thedouble-tree.

This invention relates to new and valuable improvements in double-treesused upon vehicles; and the object thereof is to construct thedouble-tree in a manner wherebyr the same is rendered convenient to theteamster in changing the direction of the traces from a horizontalposition to any angle desired.

The invention consists in providing the double-tree with pivoted arms,to which the clevis of the ordinary whifiietrees or singletrees areconnected7 and means for holding said arms in a horizontal position, orat any desired angle therefrom, as will be hereinafter more fullydescribed.

In the accompanying drawings, A B represent two vertical plates havingvertical branches a at the ends thereof, said plates being held asuitable distance apart by ferrules or sleeves b, disposed between thebranches a and held by screw-bolts c, passing through the ferrules orsleeves and ends of said branches, the bolts being confined by nuts d.Any other suitable means, however, may be employed for holding theplates apart, as found most convenient.

Between the plates A B is fitted a block, c, its ends being cut away, orhaving a semicircular recess to receive the rounded ends of arms O D,which are pivoted between the plates A B by pins f, passing through themand the plates. These arms, when in a horizontal position, asillustrated in Fig. l, which is the same as the ordinary double-tree,are firmly held in that position by a gage-pin, g, passing through thebranches a and through the arms.

To the outer ends of the pivoted arms C D are connected, in anywell-known manner, the clevis of hthe ordinary whifietrees orsingletrees, to which the traces are attached.

When it is desired to change the direction of the traces the gagepin gis withdrawn and the arms C D brought to the desired angle above orbelow a horizontal line, as. illustrated in Fig. 2, and held there bythe pin g. Any other suitable means may be used for.holding the arms atthe positions required, as I have simply shown one of many devices whichmay"P be adapted to the purpose.

It should be understood that the pivoted arms are adjustable independentof each other, and therefore one pair of traces may be raised or loweredwithout disturbing the other pair, so that the traces of one horse mayrun hori zontal while the other is inclined downward to suit therelative capabilities of an ill-matched team, as it is generally'understood that the higher the traces are attached to the load the lessstrength the animal can exert, and, vice versa, the lower the point ofattachment the more strength the animal is capable of e2;- erting.

Having now fullyldescribed my invention,

,what I claim as new, and desire to secure by Letters Patent, is-

A double-tree for vehicles, consisting of the pivoted arms C D, withmeans for holding said arms at a horizontal position., or at any desiredangle, substantially as and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

WILLIAM W. WINEGAR.
